Filter by:The purpose of the study is to research the association between receiving Tysabri® (natalizumab), interferon beta-1a, glatiramer acetate or not having any treatment for your MS and how it may or may not impact certain white blood cells and other immunological markers. This information may be useful in identifying risk factors in developing progressive multifocal leukoencephalopathy (PML). It does appear that the risk increases with the total number of natalizumab infusions. Patients who have not yet started a disease modifying therapy or who have been on one other than natalizumab are needed as controls to see how these biomarkers change. Patients at various stages of natalizumab treatment as well as natalizumab naïve are needed to allow for analysis of the change in potential markers over time.
A 12 month study where 852 patients with relapsing remitting MS will be randomized 1:1 to fingolimod or approved disease modifying therapy. Patients will be be treatment naive or have only been treated with one class of DMT (Interferon beta preparation or glatiramer acetate) . Patients will be able to switch to different treatment for safety, efficacy, tolerability or convenience during the study. Primary objective is to evaluate efficacy of fingolimod by assessing patients retention on treatment. Secondary objectives are to compare reasons for discontinuation, adverse events, cognitive impairment, medication satisfaction and change in brain volume measured by MRI.
Background: - Research shows that both genes and the environment influence a person s risk for getting multiple sclerosis (MS). However, it is not possible to accurately predict who will develop MS. Researchers want to study people with MS and their family members. They have developed a Genetic and Environmental Risk Score for MS. This score combines information from a person's medical history and genes. It also includes environmental factors that may be related to developing MS. This study will test this risk score to see if it can help predict who will develop MS. Objectives: - To evaluate a score for genetic and environmental risk factors that may help predict whether a person will develop MS. Eligibility: - Individuals at least 18 years of age who have MS. - Individuals between 18 to 50 years of age who are the parent, brother, sister, or child of a person with MS. Design: - People with MS will allow researchers to look at their personal and medical data. These data will have been collected in other MS-related studies. - Relatives of people with MS will fill out a questionnaire and give blood and saliva samples. They will fill out the questionnaire again one year later. - Some relatives will have additional optional testing. These tests will include a physical exam and imaging studies. There may also be other tests. These tests may be repeated every 1 to 5 years for 20 years.
Amphetamines have been shown to improve cognition but its use is limited due to its side effects. Lisdexamfetamine is an amphetamine pro-drug, minimizing these effects and has been safely used in children and adults with Attention Deficit Hyperactivity Disorder (ADHD). The investigators hypothesize that lisdexamfetamine may improve cognitive abilities in MS patients with documented cognitive dysfunction. Because lisdexamfetamine is a stimulant its positive effects should be observed primarily in the domains of processing speed and working memory. The investigators therefore propose a study in which the primary objective will be to assess the efficacy of lisdexamfetamine in improving attention and processing speed in MS. The secondary objectives will be (a) the assessment of the safety and tolerability of lisdexamfetamine in the MS population, and (b) to test for effects of the drug on other cognitive domains, depression, and self and informant reports of cognitive and executive function demanding activities and behaviors.
An open-label extension study in which patients with multiple sclerosis received GW-1000-02 [named Sativex® in Canada and also named Sativex® Oromucosal Spray] for four weeks in an open-label manner.
A study to compare the efficacy of GW-1000-02 [named Sativex® in Canada and also named Sativex® Oromucosal Spray] with placebo in relieving five key symptoms of Multiple Sclerosis after six weeks of therapy.
An extension study to evaluate the long-term safety, tolerability and efficacy of GW-1000-02 treatment in multiple sclerosis.
The purpose of this study is to characterize the pharmacokinetic (PK) profile, safety, and tolerability of peginterferon beta-1a (BIIB017) delivered by the single-use autoinjector or prefilled syringe (PFS) in healthy volunteers to support the development of the autoinjector.
This is a randomised, double-blind crossover study to study the effect of intravenous treatment with autologous (derived from the individuals themselves) mesenchymal stem cells (MSCs) in patients with multiple sclerosis (MS).
To investigate the ability of a cannabis based medicine extract to relieve chronic refractory pain of neurological origin.
